Of course Tokyo is now in UK. They moved it to avoid further pollution from Fukushima. And the UK received a nice payment for all the land they sold, so now the British Pound is a very stable currency again.

Map is wrong. That isn't greater Tokyo, it's the Kanto region, the region in which Tokyo sits. It's a bit like drawing a map of all the home counties and calling them the area of Greater London. The map is a lie.
